The recesses 17, 18 and 19 are also so formed as to provide substantial bearing surfaces around the edges of the brick so that the strength of the brick is not substantially lessened by the formation of the recesses just referred to and to provide relatively wide bearingl surfaces completely,Y

around the brick;

formed in the brick are suitably rounded, as indicated at 22 and 23 ofthe drawings, producing in eflect arches that serve to rigidly support the top bearing face of the units when the bricks are put in use.

The brick is, preferably, hollowed out from one of the bearing surfaces for convenience in manufacture, though it should be understood that if deemed desirable, the recesses may be formed from any face yof the brick.

The recesses are preferably formed as shown in the drawings so that the sides thereof are slightly tapered. 1f desired, they may be substantially tapered, curved, or formed in any approved manner. Y The brick just described is used in the manner illustrated in Figure Ll, which shows a number ofthe bricks in usual superposed arrangement. It will be observed that the plane and uninterrupted bearing face 15 is disposed upwardly, and that the recesses open from the under bearing face of the brick, as clearly illustrated in dotted lines `in this iigure. inasmuch as the plane bearingface is presented upwardly, it will be readily understood that the bricks are laid in precisely the samemanner as an ordinary brick now in common use, the top or bearing surfaces providing the usual surface upon which the bricklayer spreads the mortar in the usual manner. It will be observed thatV when the bricks are placed upon the mortar thatV the settling of the bricks on the mortar will cause a portion of the latter to enter the bottom of the recesses 17, 18 and 19 serving to provide an interlock between the bricks and the layer of mortar. The wall thus formed is of substantially less weight than a wall formed of ordinary solid bricks. It has improved damp-proof characteristics, and at the same time the strength of the wall is not materially less than that of a wall formed of ordinary bricks, because of the manner in which the hollow recesses are formed therein.

The wall thusformed includes a multipli- City of dead air spaces providing substantial insulation from both heat and cold,so that buildings constructed from the improved brick of this'invention are cooler and more comfortable in summer and are more readily heated in winter. Y Y Y Y V The recesses in the ybrick are formed in such manner that the brick may be manu'-v factured with the same speed of ordinary brick, but at a reduced cost in view of the reduction in amount of material, and the saving of time necessary to burn or dry the brick with the consequent conservation of fuel. To this end the recesses are of sufficient length and width to enable this to be done, the length of .each recess measured in a direction parallel to the ends of the brick being more than one-halfthe width of the brick, while the Preferably the corners of the recesses .width of each recess is approximately onesixth of the length of the brick as shown on Vthe drawings.: ThatV is, each recess preferably has a cubical content approximating onetwelfth of Vthe cubical displacement of the whole brick and the cubicalcontent of the three recesses approximates one-'fourth of the displacement of the whole brick. The bricks also may be transported at lower cost because of their lowered weight.

The recesses in the brick just described,

Vmay be used toanchor bonding or tyingV elements, such elements being provided in this event with portions that may-be disposed between the layers of bricks and project upwardly into the recesses just referred to. If desired, the brick of this application may also be used conveniently to form a composite brick and-concrete wall.f Thatis, a wall in which a forni for the concrete is inveffect, produced by outer and 'inner spaced walls of a thickness ofV a single brick. In using the brick `of this invention in this way certain of the recessed bricks may be inverted so that the recesses therein opening upwardly and bonding or tying elements may be provided of a form that include projections that mayextend in the recesses that may in this event, beiilled withlmortar to firmly interlock the bonding or tying elements in the brick. The

Vcomposite wall is, of course, completed by filling the space between the outer and inner brick wall with concrete surrounding the bonding and tying elements just referred to.

The brick of the present invention is hollowed out from one face to the approximate The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning andv l range of equivalelicyr of theclaims are there-b fore intended to be embraced therein.

What I claim and desire to secure by U.

Letters Patent is l. AV brick made of burned lire clay',ishale. or surface clay inthe form of aparallelo'piped' five sides of Which are'uninter'rupted plane surfaces, said brick .being provided with a plurality of relatively Wide and long recessesY formed from the sixth side which is the bearf ing face of the brick to a depth'extending at least to the planeY parallel to said bearing face that passes throughthe center of the f brick so that thev cubical content ofthe recesses approximates one-fourthof thecubical displacement of the brick and so that the surface. area exposed to the burning action is i. enlarged, the sides osaid recesses being slightlytapered and the' corners lon the interior of the brick being rounded V so that the v Walls ,defining said recesses simulate arches. 2.

brick and to a depth of'at leastthe plane'parallel to said bearing facethat passes throughy e the center of the brick, wherebyv the surface area of the brick exposed to the burning acf tion is enlarged. t
